Wireless Security Camera

Hi,
I am trying to install a Linksys Wireless-G Internet Home Monitoring Camera (WVC54GCA). My wireless router is a D-Link WBR 1310. All goes well with the install up to the point where I disconnect the camera from the router and reconnect the power so that the camera is now working wireless. I am supose to get the messang "Camera successfully connected to the network," but instead I get the message "failed to activate connection, pease check your wireless network configuration again." I called Linksys, but they can't help me because I have a D-Link router. I don't know what it means to "check my wireless network configuration again." Any help on what this means, or where I should go from here would be greatly appreciated.
Thanks,
Pete
